The invention describes a USB expansion device which comprises a circuit adapted to provide a USB header output and at least one USB output and a connector adapted to connect the device to a USB header located on a motherboard. The device may be modified to include a connector which is adapted to connect with a motherboard USB header socket; two or more USB connectors; and a circuit adapted to manage the USB output and a USB header output. The invention is designed for use with internal USB devices and allows them to be connected to the USB without requiring that known conventional external USB ports on a computers be connected directly to the internal component. Alternative embodiments include hub variations which allow internal USB expansion without the use of PCI cards or rerouting of USB connector cables from the exterior of the computer.
